Start with what you own. Just the right order.

No one-size-fits-all routine. Corneo puts what you own in the right order.

Your shelf becomes a routineFive products on a shelf: a retinal serum, a glycolic toner, a vitamin C serum, a moisturizer and an SPF 50. Corneo checks them: the retinal and the glycolic are not used on the same night (rule H2), and the sunscreen is required with a retinoid (rule H1). The glycolic is held back and comes back once the retinal is settled. The rest are sorted into a morning routine (vitamin C, moisturizer, SPF 50) and an evening one (retinal, moisturizer). The retinal starts at 2 nights a week, Monday and Thursday, and works up to 4.

Try it

Same shelf. Different skin.

No one routine fits everyone. The same five products, and the routine Corneo builds from them for two different people.

Morning

  • No cleanser on this shelf
  • Vitamin C serum
  • Moisturizer
  • SPF 50

Evening

  • No cleanser on this shelf
  • Retinal serum
  • Moisturizer

Held back

  • Glycolic toner

One active at a time makes it possible to tell what is working. This comes back once the first one is settled.

Built by the app's own rules engine, not drawn by hand. The shelf has no cleanser, so that step is a gap in both.

How it works

  1. Audit your shelf.

    What goes in tonight, what conflicts, what waits.

  2. Fill the gaps, not the cart.

    A suggestion only for a missing step.

  3. Step up only after you log the nights.

    2 nights a week, more only once those nights are done.

Why I built Corneo

I wanted a skincare routine backed by science, not by whoever had the biggest ad budget. The more I read, the clearer it got: what works depends on your skin, what you already own, and how fast your skin can adapt, so no single routine fits everyone. I built Corneo to check every product against published dermatology guidance and build the routine around you.

Questions

All questions

Does it scan my face?

No, and it never will. The only photo Corneo reads is your shelf, to read the labels. A photo of your face or skin is never an input to your routine.

Which products does it recommend?

Only ones from a short catalog chosen by hand, and only to fill a step your shelf does not cover. If you already own something for a step, that is what goes in. For most people who arrive with a routine, the gap is sunscreen or nothing. Nothing is ranked by what it would earn Corneo, and each entry shows why it was chosen.

Does it work if I already have a routine?

Yes. That is Audit mode: with three or more products on your shelf, Corneo leads with what it found about what you own instead of a prescription. What checks out stays, and what conflicts is set aside with the reason and the condition that brings it back.
